I was going to say that for over a decade YS has had a section next to it in the pastebin that says they do a fixed markup on their tea each year so some older teas that they've had in stock for a while are wildly out of sync with the rest of the market, but it seems it's not there anymore. It probably should be. It's only really a nice source for bulk loose leaf stuff like longjing or cheap oolongs, it's not the best place to be buying puerh, I don't think I've purchased a cake from there in years.
